for transforming the 'current'into a direct-fi current whereby the magnets `'of a magneto..

' of aninternal combustion engine may be re magnetized quickly with the mimimumamount of labor inl order that it will havev -the highest possibleetliciency. y y

A further ob'ectis to devise a deviceof vthe kind referred to above which in addition to being capable of remagnetizing magneto magnets can be used for recharging storage batteries. f

A still further object is to dev'ise'means whereby thercctilied current .can be varied.

Our inventionconsists of a device for reinagnetizingA magneto magnets constructed and arranged all as hereinafter more par- .ticularly described and illustrated in the accompanying drawing -in which:

Fig. 1 is a front elevation of our device. Fig. 2 is 'arear elevation of the device showing the rectifier cells in section.

Fig. 3 is a-l'arge sectional detail showing means for adjusting the plates of the rcctif lier to increase or decrease theI resistance hetween the plates.

In the drawings like characters of reference indicate the corresponding parts in cach figure. 1 1 indicates a casingr which is provided with an' open back and which is' secured against the wall of the garage.A 2 indicates a double 45 pole indicating vsnap switch. 3 indicates aplug receptacle by which the devi-re is con- 'nected to the terminals oi the magneto lor the battery. 4 and 5 are the Wires of the alternating circuit. The wires tjand 5 lead 5f) from the terminals 6 and 7 of the switch 2. Sand 2 are. wires leading from the. opposing terminals of the, switch 10 .and ll. l2 is nur rectifier provided with cells 13, 14,.-15, and 1G in which are lin-ated adjustable eleca5 -trode plates 17, 18, ici and 2U preferably formed Volffaluminum. 21, 22, 23, and 24; are stationary lead electrode plates. 30 indicates the cover extending over the cells 13, 14, 15 and 16 and .formed of an insulating matexi'al such as rubber.' The lates 21, 22, 23 and o0 24 are secured in a stationary position to the cover'30. 31 indicates slots formed in the cover 30. 32 indicatcsslide plates bearing .against the lower face of the cver and carrymg the alummumplates 17, 18, 19 and e5 21).'j 33 indicates studs extendingV from each` plate 32 through the slots 31. yThe studs 33 I are connected together by a wooden rod 34. By this means all the plates 17 18, 1 9`and 20 may bemoved either towards or away 70v from the stationary plates so as togincrease the resistance. It will of course be under` "stoodthat the cells are filled Awith a suitable Ielectrolyte such as al solution of approximately 24.younces of sodium sulphate, and 6 75 ounces of sodium phosphate to four quartsof Watch". 25 is a bridging wire connectingjshe stationary plate 21 to the movable-plate 19.

. 2G is a bridgingwire connectingthe stationary plate 22 with the movable late20. 27 is a so wire connecting the movabxle plate 17 with\ one terminal of the plug receptacle 3. 28 is a wire leading from the other terminal of the plugreceptacle 3. 35 is a wire leading from the plate 18 being tapped at its opposite end 95 into-the wire27. 36 is an ammeter provided with terminals 31' and 38. The wire 28 hereinbefore described is connected with the terminal 38. 39`is a wire connecting the other terminal of the ammcter with the plate 24. lfVhen it is-desired to remagnetize the magnets of the 'magneto the plug of the' lead Wire leading from the terminals of the hat tery or magneto is inserted in the, lug reccptacle 3 and the switch 2 turned) in the 95 closed position thereby forming the following circuit extending from the wire 4: and switch terminals 6 to the terminal 11 and wire 8 leading to the bridging wire 25, then through the stationary lead plate 21,"mov- 10o 'able aluminum plate l7`and Wire 27, to one termi-nal of the plug receptacle which is `connected 'by the plug to theother terminal 'and the circuit passing from thence to the wire 28` to the terminals 38 and, 37 of the 105 ammeter 36 then hy Wire-39 to plate 24, from thence to plate 20, to the bridging Wire 2G and then by wire S) to the other terminal l() of thc switch crossing the switch at the terminals 7 and out by wire 5. At the junc- 11|.)

through the wire 39 also divides, av portion of the current passing through the Wire 40, plate 23' and plate 19, Wire 41 -leadingb back into the circuit at the junction of the Wire 8 with the bridging Wire 25.

l10 It is found that the magnets of magnetos become demagnetized and heretofore in .-order to remagnetize the magneto it had to be removed and replaced 'involving the exenditure of t\v.0,days work. By our 'deli vice all that is necessary to do is to connect the terminals of the magneto .to the plug receptacle 3 and to turnnon the current by the SwitchQ., The current passing through the electrolytic rectifier is transformed from alternating current into a direct current.

withfwhich the magneto is remagnetize'd 'the whole operation beinlgr accomplished in a few minutes the result being 4that the magneto 'is in a much higher state of efficiency 25 lfthanjf it were reniagnetized in the ordinary way. This results 'in a hotter sparlc with a consequent increase in power.

If desired a, tester 43 may be employed in connection with our device the termina-ls of which are connected by wires 44 and 45 to the plug receptacle 46. When it is desired to test the magneto the plug is inserted in the plug receptacle 46 and connected to the' vmagnetoterminal in the sameway as when being remagnetized.

v` Although the device Yis particularly appli- ,cable to use in relnagnetizing magnetos will be-seen that it can be used as a rectifier for charging batteries.

Further the current in either case; can be readily varied by moving the movable electrodes closer to or away from the stationary electrodes, thus descreasing or/'increasing the resistance. p 'ff t. i
